1. Use brute force during installation. Directly tapping the bearing with a hammer will cause the greatest damage to the bearing; it is the main cause of deformation.
2, the installation is not in place, the installation is biased or not installed to the bearing position, resulting in too small bearing clearance. The inner and outer rings are not in the center of uniform rotation, resulting in a small ball mill of different hearts.
Recommendation: Select an appropriate or professional bearing installation tool, and use a special instrument to detect it after installation.
Second, poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main causes of premature bearing damage, coal gangue crusher. The main reasons include: not adding lubricant or lubricating oil in time; lubricant or lubricating oil is not filled in place; improper selection of lubricant or lubricating oil; inaccurate lubrication method, etc.
Recommendation: Choose an accurate lubricant or lubricant and use an accurate lubrication method for the ball mill manufacturer.
Third, pollution (about 14%)
Contamination can also lead to premature bearing damage, which means that dust, metal chips, etc. enter the bearing. The main reasons include: opening the bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is contaminated by the impact crusher.
Recommendation: It is best not to disassemble the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; and strengthen the bearing seal.
Fourth, tired (about 34%)
Weakness damage is a common type of damage to the spiral sand washer. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; improper maintenance; equipment aging.
Recommendation: Select the appropriate bearing type and replace the price of the fatigue bearing crusher on time.
The above are the most common causes of early damage to the bearing; the cause of early damage to the bearing is multifaceted. The above is the main reason for consideration, and sometimes it may be a comprehensive cause. If the bearing selection is accurate, the installation method is accurate, the lubrication method and the lubricant selection are accurate, and the bearing is a ceramic ball mill that can work normally for a long time.
